Flash Security policy configuration (1)

When flash communicates with JSP recently, flash cannot send messages to JSP. It was really depressing. I read the official document and found a simple solution. The first official solution is user management control. This global solution solves the problem of communication between flash and JSP.

 

 

The solution is as follows:

Step 1

Find the path directory in the system:

C:/Windows/system32/macromed/flash/flashplayertrust

 

FlashplayertrustThis folder is a trusted area.

 

We can see several files with suffixes, XXX. cfg. To solve the communication problem between flash and JSP, I create a text named Dev in this directory:

 

 

Step 2:

Create the dev.txt text and write the directory where the flash file is located. I put the directory in the test folder of the idisk, and then changed the suffix to the cfg file.

Dev. cfg file

 

 

File directory:

 

 

 

After preparation, test our file:

Prepare a JSP file, as shown below, and accept the two messages returned by the client.

<% @ Page Language = "Java" pageencoding = "UTF-8" <br/> %> <% string username = request. getparameter ("username"); <br/> string userpwd = request. getparameter ("userpwd"); <br/> out. println ("MSG =" + username); <br/>%> </P> <p>

 

 

Prepare the client: perform a simple test.

 Package <br/> {<br/> Import flash.net. urlloader; <br/> Import flash.net. URLRequest; <br/> Import flash. events. *; <br/> Import flash.net. urlvariables; <br/> Import flash.net. urlloaderdataformat; <br/> Import flash.net. *; <br/> public class connect extends eventdispatcher <br/> {<br/> // URL of the connection <br/> Public static const myurl: String = "http: // localhost: 8080/flash2/receive.

Package <br/> {<br/> Import flash. display. sprite; <br/> Import flash. events. *; <br/> Import flash. text. *; <br/> Import flash. display. simplebutton; <br/> Import FL. controls. button; <br/> Import flash.net. *; <br/> public class main extends sprite <br/>{< br/> private var con: connect; <br/> private var Username: textfield; <br/> private var PWD: textfield; <br/> public function main () <br/> {<br/> con = new connect (); </P> <p> Init (); <br/>}</P> <p> private function Init (): void <br/> {</P> <p> username = new textfield (); <br/> addchild (username); <br/> username. width = 200; <br/> username. height = 20; <br/> username.

X = stage. stagewidth/2; <br/> BTN. y = stage. stageheight/2 + 50; <br/> B Tn. addeventlistener (mouseevent. click, sendhander); </P> <p >}< br/> private function sendhander (E: mouseevent): void <br/>{< br/> If (username. text! = "" & PWD. Text! = "") <Br/>{< br/> trace ("Send OK"); <br/> var para: urlvariables = new urlvariables (); <br/> para. username = username. text; <br/> para. userpwd = PWD. text; <br/> con. sendmessage (para, connect. myurl); <br/>}else <br/>{< br/> trace ("Empty message cannot be sent "); <br/>}< br/>}

 

In this way, you can simply send the information, because the program can still be improved here, lazy, mainly describes the security configuration problem.

 

 

 

In the program, we should be careful

Public static const myurl: String = "http: // localhost: 8080/flash2/receive. jsp ";

 

Our SWF file is not in the Tomcat directory, as long as it is in another disk. During local testing

C:/Windows/system32/macromed/flash/flashplayertrust

 

Add the directory where the SWF file is located to solve this simple problem. Now you can communicate.

 

 

Note: problems caused by the firewall may sometimes intercept messages, so it is no longer necessary to close the test. Of course, this is only a special case
